2The Basics
This chapter introduces important basics about your PowerBook that you’ll want to know. Getting to Know Your New PowerBookBecause your PowerBook is so thin and light, you can take it with you to the office,
library, class, or wherever you work or play.
Whenever you stop using your PowerBook, wait a few moments to let the hard disk
and any optical disc in your drive stop spinning before you transport the computer.
Avoid jostling or bumping your PowerBook while discs are spinning.
Note: Your PowerBook uses Sudden Motion Sensor technology to help protect the
hard disk should the computer be dropped or experience extreme vibration. See
“Sudden Motion Sensor” on page 48 for more information.
When using your PowerBook or when charging the battery, it is normal for the bottom
of the case to get warm. For prolonged use, place your PowerBook on a flat, stable
surface. The bottom of the case is raised slightly to allow airflow that keeps the unit
within normal operating temperatures.
As you get to know your new computer, you may hear small noises during startup and
when using your hard disk and optical drives. For example, your hard disk and optical
drives may whir and click as they access information or load and eject discs. After the
PowerBook runs for some time, a small fan may turn on to cool it, producing a faint
sound. Small noises are part of the PowerBook’s normal functioning.
For more safety instructions about handling and using your PowerBook in different
locations, be sure to see Appendix B, “Safety, Use, and Care Information,” on page 73.
